沉默警告在熊猫

Question

在运行时：

mydf = pd.read_csv(p_file, sep=',', error_bad_lines=False, index_col=False) 

我得到许多线像下面这样：

... 
Skipping line 77432: expected 15 fields, saw 16 
Skipping line 77497: expected 15 fields, saw 16 
Skipping line 77528: expected 15 fields, saw 16 
Skipping line 77560: expected 15 fields, saw 16 
Skipping line 77625: expected 15 fields, saw 16 
Skipping line 77656: expected 15 fields, saw 16 
... 

我怎么能沉默这些警告？我如何找到Pandas中的警告类列表？

Answer 1

看起来read_csv有warn_bad_lines kwarg，所以你应该能够做到以下几点：

mydf = pd.read_csv(p_file, sep=',', error_bad_lines=False, index_col=False, warn_bad_lines=False) 

http://pandas.pydata.org/pandas-docs/stable/generated/pandas.read_csv.html#pandas.read_csv

“如果error_bad_lines是假，而warn_bad_lines是真实的，警告每个“坏行”将被输出（仅在C语法分析器中有效）。“
